Answer 1

Answer:

D

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Given

$\sqrt{3}$ ($\sqrt{3}$ + 2$\sqrt{12}$ ) ← distribute

= 3 + 2$\sqrt{36}$

= 3 + (2 × 6)

= 3 + 12

= 15 → D

Answer 2

Answer:

sqrt3[sqrt3+2sqrt12]=sqrt3[sqrt3+4sqrt3] = sqrt3[5sqrt3= 3x5 =15
